`Bc itlnown that LHENRY A; HOUSE, a citizen dfftlie United States, and a residentof Bridge ort, in the county ofFairield and State o onnecticut, have invented certain newand useful Improvements in Spring- Controllers, of which the following is a speel-- ication.

My controllers, and it has for its object to provide a controller'for the springs of automobiles and vehicles of like character which and readily made ad-` will be both ieldin justahle to tie load. i To this end I have employed the hydrostatic system, which consists in suhmerging the )umps orcylinders in a liquid within a tiglitly sealedv case or chamber devoid of working or other avenues of escape for the liquid, which working packed joints arecommonly found in devices employing Ithis system.

range a graduated scale or index on the exterior of the ca'se whereby the controller can be readilyadj usted to suit the load or weight el the automobile or car to which the con" troller is attached. Y

',lo enable others to understand my inven tion reference is had to tl1e accompanying drawings, in which: t

. 3` is the pum case, having the flange 4 by means ofwhici it is vsecured tothe side of the frame by the bolts 5. 6 is the cover for the pum case. crank-shalt which is joui-na ed in the u per part ofl said case and it is operatively ield. therein by the lange portion a of the cover, asseen more clearly at Fig. 7. Y

8 (see Figs. 4 and 9) is an arm integral from the crank-shaft whoselower end is pivotally connected to the piston 9 operatively mounted. in the ump cylinder 1U. .This connection is efected through the medium of the pin 11 ex `tending through the head portion 9a of' the piston..

12 are holes in the head of the` piston for the admission of liquid from the interior of the case to the interior ofthe ump.

` 1B is a block of elastic cor r,`the ohieot of which will hereinafter he more fully deA scribed. This cork is mounted. on the llange 14:, 'which flange, is endwise movahly sup- 7 is the ported on the stationary screw 15, and '16 is a packing adapted to close the pressure of the endof the iston.

yThe hea portion 10n inserted in the recess 17 4(Fig. El) ol' the end wall of the case and it has the hole 18 (Fig. 13) therethrough by means ol' u-hieh it is piv connected. to the pump hinge pin 19, having the transverse port 20 therethrough, as also seen at Figs. 10, 12 and 13, which port is ada )tedto register with port 21 of the head 10'LL ol the pump. The head portion oi the hinge pin is provided with the screwdriver slot 22 (Figs. 4l. and 9), and 23 is a' shortL shalt journaled in the cover 6 (see also l? ig. 5) whose inner end is provided with a screw driver-like point 22%,which point is adapted. to register with the slot 22 in the hinge pin. The projecting end ol' this shaft (see also Fig. l.) carries the indicating hand 24 adapted to he moved over the dial or registering scale 25 on the outside ci the cover 6. The outer end ol the shalt 23 is squared to receive a wrench so'that' the hinge pin may berota tively adjusted with respect tothe resistance theports 12 when liquid is on the opposite ol the pump is freely r .the ear itself added to the bload carried by the r sorted in the lower end of the nut 35. The

offered to the istoii and the load sustained by the car. T iis resistance is in the form of glycerin or other like non-evaporating liquid with Which the case 3 is filed. The backward stroke ol the piston Will draw the liquid througli the ports l2 into the interior of the pump by forcing back the packing 16, and the forward stroke will close said ports. As beforementioned7 the resistance offered by the non-compressible liquid to the piston on its l'orivard stroke, is proportional to the load i or weight ol' the car, and is regulated by the amount olI opening of the liquid discharge iort, and this opening is readily determined iy the scale 25 on the exterior ol' the case cover.

lel'erring to Fig. 1, when thc'hand 24' is brought to ther zero mark on the scale,.-it will indicahie a l'ull open discharge port,` as shown at Figs. t) and 10, with no resistance on the piston. T he other marks on the scale from 1 to 7 will indicate dierent openings of the discharge port and varying resistance on the piston corresponding' to said openings.

ball 36 operates in a circular seat in the head portion 37 of the plate 38, which plate is secured to the car springI by the clipsl 39. The parts 34, 35 and 36 l'oriii an adjustable connection between` the lever 33 and the car spring 2.

The adjusting arm 29 has the depending socket portieri 29 (F 1 and (i) in Whose open threaded mouth is located the adjust ing the large compression spring-fil and the llexiblc riding spring 42, 43 is ahousing also lfig. 8) Whose ears 43 embrace the lever 33 for centralizing said housing. The lower end of the flexible riding s' ring-42 rests, as before mentioned, on the a( justable plugllO, while its upper end seated at the bottom oi' the open mouth ol' the housing. The upper'end of the compression spring 41 engages with the lug 14. A groove (not shown) in the head portion 42% ol' the housing enables said housing to be depressant by or past said lugivithout contactingr tluiievvitli. 45 is an adjustable screw in the crank adjustH When the indicating' hand is moved to the mark X on the scale it Will indicate that the discharge port is fully closed. 'lhe value ol' each mark on .the scale can be predetermined so that each mark will indicate the'load to be sustained. In. other Words, the Weight of car. By means otl this visible scale and indieating` hand, it will readily be seen how easily ingarni '2Q whose point contacts u'ith the lever :i-.

As ther(l is more or loss variation laitu'oon the frame and springs ol dill'orent make ol' cars, l am able to readily adjust )my iinproved eoiitroller to any car by means olI the toothed sleeve 2G and the toothed hub portion of thoarni 29. When the car standing still, the normal position ol' the pump piston the controller can be accurately and quickly set for the Weight and varying load' of an car. In attaching devices of this character to ears, they are adjusted to conform to the I weight of the car plus the load the car is capablo oll carrying so that, if the car is built to carry seven persons, the adjustment is made to correspond thereto and if at an time the number be less, the car will lack the proper resiliency for easy riding. But with iny improved means olA adjustment, the slightest variation in the load can be quickly taken care of.

2o (Figs. 2, 3 and 7 is an adjusting sleeve having the teeth 27 on its vertical face adapt ed to register ticil lace ol' the li ub portion of the crank adjustine` ariii Z'S The sleeve 26 has the heX- agoi'i center 30 adapted to have a sliding lit on the hexagon end Y (Fig. 11) of the crank 1. The ai'iii 25,) is mounted on the vflange portion 26 ol. the sleeve 26 and said sleeve and .vaslier 132, shown at'Figs. l, 2 and 7.

F5255 is a lever pivotally supported on the arm Zt) by the pin Sil- The opposite end of j this lever is provided with the ball 33 to j and arm are held in place by the screw 3l j work in 'a circular seat i'ornied in the head.

ft; is a ball having the threaded shank in- 'wi'th the teeth 28 on the veri is at its extreme outward sti-olio as shown at Figs. 4 and t). To adjust the fontrollcr to the varying distances, the arm 2S) is teniF porarily removed and the crank shalt rotatod to properly locate the piston, and as the sleeve 26 (Fig. Si) has a hexiuron bore and an odd number oi' teeth, it will be readily seen that any amount oi' variation in the height 'ol' the free or ball end ol the lever 3 can be had by simply placing, the adjusting sleeve in. the proper position on the hexagon end of the crank-shaft, while lor a minute adjustment the connection between the end oi' the lever 33 and spring' 23 can be secured by means ol' the long` nut 3.5. k

The riding spring 42 t(gives a limited vertical movement or yplay to the end ol the lever 33 i'or `the normal vibration olA the ruiming gears of the ear; but when a sudden jolt oc curs and abnormally de resses the car spring, its sudden reaction is ciecked by the piston 9 acting against the liquid. iii the pump, which liquid will be l'orced out or' lthe pump in quantities proportionate to the ,load sustained by the cai'. ln other words, the greater' the load the slower the liquid will escape and, consequeiitly, a slower reaction or recovery of the l'raine to anormal condition will. be the result. The advantage dcrived from being able adjust the escape ports oi the pump by means ol' the indicating hand and dial or scale to the load, and to do able threaded plug 4() supporting and adjust-` this from the greatly ep B37 menue Iluture oll the coil'.
